Abstract
This paper presents a novel approach to reducing sulfur dioxide (SO2) emissions from sulfur recovery units. The proposed technology is a cost-effective tail gas treatment solution capable of achieving over 99.99% sulfur recovery. XILSORB technology uses porous sorbents in two consecutive stages: the first stage dries the tail gas stream, while the second captures and removes SO2 from the dehydrated stream.
Experimental results from the research phase demonstrate that the SO2 adsorption capacity and SO2/CO2 selectivity position XILSORB as a competitive alternative to existing commercial processes.
XILSORB technology is expected to achieve sulfur recovery rates exceeding 99.9% in gas plants and refineries, while also reducing capital expenditures (CAPEX) and operating costs (OPEX) by at least 30% compared to commercial reduction-absorption processes for managing SO2 emissions at 50 ppm.
KEYWORDS: sulfur dioxide emissions, adsorption, tail gas treatment, sulfur recovery units, operational and capital expenditures, 3A and 5A molecular sieves
